Hydrogen is the chemical element with atomic number 1. It is the lightest of all elements with an atomic mass of 1.00794 (7) u and the most abundant of the universe and the Earth's crust (it represents 83.9% of visible matter). In the atmosphere, hydrogen looks like a colorless, odorless, flammable gas in its molecular form H2.
The protium and deuterium are natural isotopes of hydrogen. The most common in nature is the protium, has only a single proton and which boasts no neutron. Tritium, on the other hand, is an artificial isotope of hydrogen.

Hydrogen is present in most organic substances and acids. Even the stars, in their primary cycle, are formed by hydrogen in the plasma state.
Hydrogen is used as fuel (it can be applied in refining of fossil fuels), in the production of the ammoniacs and to hydrogenate hydrogenated fats or oils.
Experts say that hydrogen is the element that generates more power in an energy report / any fuel weight.
